壳管式冷凝器中问题的检测方式和维修

人气:0 评论:0 日期:2019-07-28 22:32:25

既然中央空调是一种制冷设备,那它肯定配有冷凝器,而且多数是壳管式冷凝器。当装置经过了长时间的使用之后会出现一些不便利的情况。这时候,用户要做的就是对壳管式冷凝器进行检查和修理,也是为了能让中央空调使用的更长久。若是发现中央空调的制冷能力有所下降的时候,应该先检查一下其中的壳管式冷凝器是否完好,有没有出现损坏的情况。因为使用时间长了之后,壳管式冷凝器的管子接口进程会出现松弛的情况,并且管子处也会因锈蚀而导致砂眼、裂缝等缺陷的产生。我们检查的重点就在这些地方,再一次确认壳管式冷凝器识正常的。

Since central air conditioning is a kind of refrigeration equipment, it must be equipped with condensers, and most of them are shell-and-tube condensers. When the device has been used for a long time, there will be some inconvenience. At this time, the user has to check and repair the shell-and-tube condenser, also in order to make the central air-conditioning use for a longer time. If it is found that the cooling capacity of central air conditioning has decreased, it is necessary to check whether the shell-and-tube condenser is in good condition and whether there is any damage. Because the tube interface process of shell-and-tube condenser will be relaxed after a long time of use, and the tube will also be corroded and lead to sand holes, cracks and other defects. The focus of our inspection is on these areas, once again confirming that shell-and-tube condensers are normal.

但如果壳管式冷凝器的这些方面确实存在问题的话,紧接着就可以利用水压测的测试的方法,对壳管式冷凝器出现的问题进行检漏试验。在检测过程中,当壳管式冷凝器中的水压升高到一定程度时,就可以以将泄露部分准确的定位,我们可以用一些容易留下痕迹的标记物,便于后期的维修。

But if there are problems in these aspects of shell-and-tube condenser, then the leakage test of shell-and-tube condenser can be carried out by using the method of hydraulic pressure measurement. In the detection process, when the water pressure in shell-and-tube condenser rises to a certain extent, the leakage part can be accurately positioned. We can use some markers which are easy to leave traces for later maintenance.

根据以往的经验来说,如果是壳管式冷凝器管子内部因腐蚀而造成泄露情况时,想要检查出来的可能性就比较小了。这种情况下,就要用一些化学物质建议检测,主要是看所排出的水是否有颜色上的变化,从而找出泄露原因所在。

According to past experience, if the leakage of shell-and-tube condenser tube is caused by corrosion, the possibility of detection is relatively small. In this case, it is necessary to use some chemicals to suggest detection, mainly to see whether the discharged water has a color change, so as to find out the cause of leakage.

壳管式冷凝器有了明确的受损位置和受损原因之后,修理起来才会更加的简单,壳管式冷凝器也能更快的恢复正常,减少不必要的损失。

After the shell-and-tube condenser has a clear damage location and causes, it will be easier to repair, and shell-and-tube condenser can return to normal faster and reduce unnecessary losses.
